• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sac) OR (vu san)) ky lang van hoi. hieu van cac loc va ((tinh ca) or (tinh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sac) OR (vu san)) ky lang van hoi. hieu van cac loc va ((tinh ca) OR (tinh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sac) OR (vu san)) ky lang van hoi. hieu van cac loc va ((tinh ca) or (tinh va)) cua tre*".
